Substitute cheap supplements development for Pleurotus ostreatus cultivation usiug food by-product dried wastes

음식부산물 건조박을 첨가한 배지에서 느타리버섯의 균사생장 특성

The combination ratio of oyster mushroom cultivation supplements have used poplar sawdust(PS) 50% : beet pulp(BP) 30% : cotton seeds meal(CS) 20%. we substituted cotton seeds meal and beet pulp for food by-product dried wastes(DW) 10, 20. 30% respectively. In case of mixing with DW 10% except from BP, mycelial growth was inhibited a little, but mycelial density was accelerated. The more DW contents increase, the more mycelial growth was inhibited, but mycelial growth was accelerated a little, respectively. In case of mixing with DW except from CS, mycelial growth was similar to control almost. In case of mixing with DW except from CS and BP, mycelial growth was inhibited remarkably. CHUNCHU variety developed resistance to developed than SUHAN variety.

느타리버섯(수한, 춘추)의 음식부산물건조박 대체 효과실험을 위하여 기본배지(대조구)를 포플러톱밥 : 비트펄프 : 면실박을 5 : 3 : 2(v/v)로 하여 대조구의 면실박 20% 대신에 건조박을 10% 혼합하였을 때 10일간의 균사생장길이가 수한 1호는 63mm, 춘추 1호는 68mm이었다. 이는 대조구의 수한 1호 67mm, 춘추 1호 74mm 보다 균사생장속도는 약간 느리지만 균사밀도는 높아 대체하여 사용할 수 있음을 확인하였다. 그러나 건조박의 혼합비율이 20%와 30%로 높아질수록 균사생장속도는 늦어지고 균사밀도는 높아졌다.
